I think because it's like in hopscotch you remix someone else's projects you get their username above yours so since hopscotch used http://www.discourse.org to make the hopscotch forum so because on discourse you can't make projects so discourse should get a profile.

Hi like @BuildASnowman said, Discourse is what this forum is based on. The makers of Discourse have accounts here too, and I think it's so they can check up on the forum if things go funny behind the scenes.
